After struggling past Kateryna Bondarenko 7-6(4), 6-7(5), 6-4 in the second round of New Haven, Elena Dementieva says she is still struggling mentally and physically after suffering a calf tear at the French Open.

"I’m not good at giving percentages but I am still not 100 percent coming off that injury," she said. "It took me a long time to get better. I was playing so well in Paris but you just have to deal with it. It was a disappointing moment for me, especially having to miss Wimbledon.

"I feel like this isn’t my summer," she added. "But sometimes a long match like that will help you improve."
